Origin

A band in the sense ‘a strip of something’ comes from the same Germanic root as bind (Old English) and bond (Middle English). Bend is a variant found in bend sinister (early 17th century), a broad diagonal stripe from top right to bottom left of a shield, a supposed sign of bastardy. Bandage (late 16th century) and bandbox (mid 17th century), now a box for carrying hats, but originally for carrying neckbands, come from this word. In early use a band in the sense ‘a group’, usually consisted of armed men, robbers, or assassins. The first groups of musicians called a band (in the 17th century) were attached to regiments of the army. Banner (Middle English) is related. A bandwagon (mid 19th century) was a wagon used for carrying the band in a parade or procession. The word now occurs more often in phrases such as to jump on the bandwagon. This use developed in America in the late 19th century.
